With its computer animated video and up-to-the-minute audio mix, Happy Feet is far more dazzling technically than March of the Penguins. Here we have the same sort of penguins as before, but with a smaller species thrown into the story as well. The life-cycle/survival situation here is the same, but in this film it's a backdrop for the plot. The penguins here are a lot more communicative. They talk, sing, and dance almost constantly. Or rather, Mumble, our hapless hero, dances. While the other penguins sing, he can't warble a single tuneful note. But he's Gotta Dance.
